Title: Vacuum valve
Inventor: OKUTOMI ISAO
IPC: H01H33/66
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To stabilize an arc by the generation of magnetic flux in an axial direction between the magnetic poles by using a magnetic body which does not have the shape of closed loop, so that the end parts thereof act as the magnetic poles, and further making a counter electrode generate the magnetic pole on the end part of the magnetic body. SOLUTION: Current-carrying rods 2 are fixed to a point of a current-carrying rod 1 on a circle, concentric with the current-carrying rod 1, and magnetic bodies 3 are respectively installed near the current-carrying rods 2. When electric current in a predetermined direction, is flowed to the current-carrying rods 2, a generated magnetic flux C is passed inside of the magnetic body 3, thereby both ends 3a, 3a of the magnetic body act as the magnetic poles of the polarities opposite to each other, because the magnetic body 3 is not a closed loop. Here, the current-carrying rods 2 and magnetic bodies 3 of the same shape are installed on a mutually facing electrode, thereby the different magnetic poles are generated, because the directions of the electric currents flowing in the current-carrying rods 2 are opposite to each other in the electrodes. Thereby the magnetic field in an axial direction is generated between the magnetic poles of the magnetic bodies opposite to each other. That is, the magnetic field in the axial direction can be generated with a simpler structure, in comparison with a vertical magnetic field coil.
